The practice of preserving critical site knowledge when crews rotate or contracts change hands. It ensures incoming workers understand site-specific procedures, hazards, and client expectations without starting from scratch. Poor knowledge continuity leads to rework, safety gaps, and damaged client relationships.
Knowledge Continuity
Related Terms
Spare Capacity
WorkforceThe portion of a subcontractor's available workforce, equipment, or service hours that is not currently committed to active contracts, representing untapped revenue potential that can be offered to clients on short notice or used to absorb surge demand without turning down work.
Field-to-Office Ratio
WorkforceThe number of field workers supported by each administrative/office employee. A ratio of 10:1 is common for paper-based operations; digitized operations often achieve 30:1 to 40:1.
CLRC (Construction Labor Research Council)
WorkforceA U.S. research organisation that tracks and publishes construction labour wage rates and collective bargaining data. Subcontractors use CLRC reports to benchmark labour costs and support bid pricing on union projects.
Demand Response
WorkforceA short-notice call-up system where operators request crews or equipment during peak production needs. Subcontractors on demand response agreements must mobilise quickly, often within hours. Rates are typically higher to compensate for the standby commitment.
Wrench Time
WorkforceThe percentage of a technician's shift spent on hands-on productive work versus travel, waiting, or admin tasks. For subcontractors, low wrench time means billing inefficiencies and reduced daily output. Clients often track it to evaluate crew productivity on site.
Rotational Worker
WorkforceA field worker employed on a fixed schedule of alternating work and rest periods, such as 14 days on and 14 days off. Subcontractors must account for rotation cycles when planning crew mobilisation and maintaining consistent headcount on site.
